Wow...thsi has got heated hasn't it.......I'm workshop controller at a Toyota dealer, i also own a Supra, I have to admit, yeah, we are expensive, £90 per hour for newer vehicles and a lower rate for older cars.
After being on the shop floor here for 7 years, i can honestly say hand on heart, I do my very best to make sure the quality of work performed is very high quality. As I write this I currently have a GT4 on a ramp with the gearbox out to rectify a fault caused by a "cheaper garage"! Basically he had a clutch replaced at a back street garage for £150 plus parts, since having the work done he has an ABS lamp on and is unable to select gears smoothly. The other garage told him that is was a gearbox fault seperate to the repair work carried out so he brought the car to us......on inspection we found that the abs sensor had been damaged (stretched) by not removing it when the shafts removed, also the clutch release bearing had been fitted incorrectly and cocked over damaging his "Genuine" clutch they supplied (it was a e bay special). So we're not charging him £280 labout plus the parts to fix all these faults.
What I'm trying to get at is, you get what you pay for....if we had made said mistakes, i'm pretty sure the car would of been fixed free of charge, and all our parts carry a 12 month warranty (with exceptions).
Please don't think that I'm saying all other smaller gargages are toss.....cause I'm not....I know loads of really talented and respected mechanics....I just wanted to put over my opinion...
Hope I added some food for thought....
