A wise man ounce told me if your buying a performance car to afford to keep it running you must be able to buy 2 of them.
Its like any car, you get some really tough ones, then you get some real lemon's.
Of course when it comes to modifying you got to totally ignore the warranty as they will totally ignore you.
I have seen some in that price range from dealers so I think you can get your hands on one with no mods.
If your looking for some thing with a little more ponies though,
I think you will have to spend a little more, cost of car and maintenance.
