Can someone education me on what to look for?

I know there's 4 & 5 lug ones. Probably gonna want the 5 lug as the car will be a 99% street car but probably start autoXing come 2010 season. Which year ones have the 5 lug.

Will terminator wheels bolt up?

Any comon problems to look for in the higher mileage ones 75k+

Would definitely be a 5speed. Only mods for a while would be exhaust & termi wheels if I could find them.

What’s a good forum or place to find used ones?

Only looking to spend $5,000.
