I have had my Jalpa for 2 years now and have been in the middle of a major overhaul for the last six weeks. If you pick the wrong car, you can easily approach or even exceed the cost of your original purchase. Parts can be expensive and hard to find. The car does not utilize belts like the old Ferraris', so you don't have those types of major engine out services like that with the Jalpa (chain drives). Valve adjustments do require the engine to be dropped. The valves can be a problem area on these cars (see Raymonds site) as well as the motor mounts. My best advice would be to buy the best example available: it will cost you less in the long run. With all that said, where else could you find a ultra exotic, rare (only 420 units ever made) fun to drive cars for the price of a honda?

ps The cost of a major service will vary greatly based on what is done once the engine is dropped. You will find that many of these cars will have all their original hoses, fuel lines, ect.... Find a car that has had a recent major done already.
