Hi - this is a good place to find advice
It really is down to personal choice. If you can get a ride in a few cars to try them then so much the better.
You will have no problem finding a car. There are always plenty for sale through traders like myself or through private sales. We (trade) can also import to order for you from Japan. Reasonable price? Depends on your budget and what you consider reasonable really.
My opinion would be for you to go for a stock car at first and develop it yourself afterwards. This allows you to get used to the car and also ensures you know what was done to the car was done correctly and (in extreme cases) has actually been truly done
There are always cars for sale. There seem more now as people tend not to buy at this time of the year.
I would buy from a trader on here (I would say that eh ) or a member as you know that the car has either been checked out properly or has been looked after by an enthusiast.
If you need any help or advice, give me a shout
