...The next best car is, and I will admit to being a little based here as I own one, is the Audi A3 1.8T. Indeed any car with this popular engine provide a great base from which to tune up from (the Audi A3 came with the stronger AGU engine with larger exhaust ports). So this includes a few offerings from Seat in the guise of the Cupra and Leon and the VW Golf, Passat and Bora and even the Beetle and wide range of models from Audi including the A4 and TT. The engine can be factory tuned to put out 225 bhp with little more than a different turbo and a remap. The majority of these cars come out with 150-180bhp with essentially the same block as the higher powered models. A small outlay of a few hundred will buy a remap which ups the power by another 50-70 bhp. Get a little more adventurous and fit a larger turbo and you will see figures of 350bhp on standard engine internals. Although quite different from the Supra the 1.8T offers much to the budget concious motorist. Firstly the engine will return upto 37mpg on a run, the service intervals are long and items like spark plugs are good for 40,000 miles. The base vehicle they reside in is commonly produced and ensures a good supply of spare parts to cover any unfortunate mishaps and the re-saleability is good with a strong demand for any car with this VAG engine fitted.
If you do not have a family, don't mind shelling out for new rubber twice a year, and are not shy the Supra is probably the ultimate choice. But sadly they are getting hard to come by - especially a non imported model which has not been badly modified. If you want one you had better track one down quickly...
