  1. The link below is to a USA based value tracker for the Supra, or indeed any model retailed in the USA giving a 5 year history on bids and sales for the car model. It isn't split into specifics on manual or auto or turbo or NA but it does show the average trend and individual information on each data point. Prices in the USA have softened a fair amount during 2023 as they did here in the UK. The price breakdown does drill down into mileage impact on pricing which is a useful guide to the depreciation curve. There is nothing comparable for the UK market but it does seem similar price trends so is a useful reference point for those watching which way the market is moving. I always felt 2023 would be peak Supra so it could be a gentle drift down from here as the cars age gracefully with precious few spare parts available to maintain them in a Toyota guise. https://www.classic.com/m/toyota/supra/4th-gen?chart=sales
  2. How would you even put one of these cars back together these days with most parts now discontinued? Maybe we will see more BMW M3 powered and propelled Mk4 Supra's as time goes on. I would expect a rolling shell in good condition with a full interior would be more in the £9k - £12k region than £20k though in today's depressing market. A TT6 VIN plate is only going to deliver value if a 2JZ-GTE engine and Getrag gearbox is returned to the car.
  3. There is currently a black carpet for sale on eBay
  4. If your vent is a replica of the UK genuine then you can generate a template from the thread for the hole drilling. http://www.mkiv.com/techarticles/european_hood_scoop_install/index.html
  5. There are differences with fuel delivery and circuitry in NA or TT or modified so it's not easy for anyone to be specific with a list of things to check. This link will give you some pointers to relay check and bypass but its specific to a TT setup which your car may or may not be. https://www.supraforums.com.au/forum/topic/73726-fuel-pump-issue-help-please/
  6. It would be impossible to say what pretty much anything is worth without pictures as rolling shells come with bits or without bits and in a variety of conditions. Bits add to the valuable. Bits like tailgates with glass worth £1k or missing £0. With or without aluminium bonnets, there is another £600. Some come with lights others don't, there is another £1,200. Some come with dented panels some come with straight panels. Some come with good useable/sellable set of wheels some come with not so good wheels. Some come with an interior, part interior or no interior. Is the shell supported on the original sub frames and drive shafts? They fetch strong money these days.
  7. I assume you will be after new bolts so Toyota would be a good place to start. Some people are happy with using recycled bolts but I have always avoided that on suspension parts as they are safety critical. With high torque bolts the threads get stretched and smoothed on first tighten which means you need a higher tightening torque to achieve the same preload you had during the first tightening. That is a think up a number exercise.
  8. Set of folding on eBay for a bargain price compared to some recent listings that have been in the high one hundreds. https://www.ebay.co.uk/itm/364036160536
  9. I had a RR that would develop a vibration between 30mph and 55mph, above or below that range there was no vibration. It turned out to be a sticky brake calliper.
  10. Here is one that is salvageable for £300. https://www.ebay.co.uk/itm/126294019044

  12. The stock wheel came in two varieties. One is composite covered giving a hard rubber feel. These do polish up a lot with use. The other much more expensive option was the leather covered wheel. Last year you could still buy the composite wheel new for around £750 from memory which isn't that bad. That is without the horn boss though that was also still available and from memory that is around £600. The leather ones are only available second hand now and those tend to start at £300 for destroyed versions. So, you can get the leather ones cheap enough so long as you are prepared to refurbish them. I bought a leather wheel 8 years ago and refurbished it and I have to say it looks good on my parts shelf. I still haven't got around to fitting it. So if you want to go tight and keep your wallet closed then this is probably the best way to proceed. I did a write up on this forum of my leather wheel restoration that you might benefit from checking out. I found it to be quite a rewarding exercise.
  13. It could be a lack of fuel pressure. Check the rail pressure then you can rule out a restricted filter, crushed pipe or failing pump.
  14. Oil films are retained on metal surfaces for up to a month. There are additives common in engine oils that attract/bind the oil to a metal surface for the sole purpose of film retention on standing. Castrol pioneered a lot of this work in the 90's and they were so proud of the new oils they marketed them under the Magnatec brand with illustrations of oil bonding to metal. The seeping away of the oil film is logarithmic with time, not linear. So you could drain your oil on a Monday and refill on a Friday and the oil film will still be 30% there from the retained old oil. If you return to a car that has sat overnight and start it up only 45% of the oil film will have been retained at that start up. So there isn't much difference overnight to several days standing, because of the logarithmic time bleed on film thickness.

    Evening ...

    Just do bare in mind that to build or to refurbish is never a sound investment. With Scooters old car you have a pretty stock example to do with what you will. 15 years ago debate raged on this forum over modified compared to stock with 2 distinct camps and at that time there was a premium price that uprated cars held over the bog standard. Today, as the car has become a modern classic the bog standard is generally worth more than a modified car. So any money spent modifying the car is likely to be spent money that may if anything, lower the value of the car. On the other investment, the refurbishment, then there are many here who have spent will into 5 figures on regenerating or renewing their cars. That is never a wise investment as for every £10 spent not many £ will land onto the value. Have fun with it, whatever you decide to do and the archive record of useful information here is probably only paralleled by the US Supra forum.
