The Delorian is an awesome car, looks wise. Good enough that it's worth it to put up with the other problems it has if you at least have a moderate amount of technical knowledge.
It isn't the most reliable car, so you would expect to be fixing things that have broken on a semi-regular basis. Though this is in general, as with all cars, some of the Delorians didn't have many problems at all, some had more mechanical issues. It was more of a gamble in which one you got. Overall it's a mighty fine car. It's like a super-car, you don't buy a Lamborghini to be practical, you buy it because it is awesome.
Also a Delorian is pretty expensive these days, A preowned with low miles on it are $45,000 to $55,000 You might be able to find a hulk for around $20,000 but you would need to put quite a bit of money into it to get it into reasonable shape.
Also the Delorian motor company is back in business, I don't think they are making any new cars, but they are making the full assortment of parts.
