Ready to race for less than £3.7k
A number of cars have been built to this budget – and some a bit under it when the owners already had seats and harnesses they could use.
A donor car can by purchased from ebay (usually not the cheapest place), from Autotrader or from Copart. Copart prices seem to be the lowest, but you must factor in their buying costs which are typically just over £100.
Quite a few donor cars have been bought for £600-700. Make sure you get the lowest mileage car available. If a donor car has done more than 100k miles keep looking.
