Re: buying a TX5.
I think you'll find the 4WS car only came out in the AY series- 92-94 (last of the Telstars). I;ve heard these cars are fairly robust so the rebuild comes as a bit of a suprise. Also...what were you doing to get brake fade? If you weren't brakingvery hard, then it may e time to change brake fluid (water gets in and causes squishy brake pedal when the calipers warm up enough). Still...$600 sounds ok.
GO and have a look on redbook.com.au and see what they says it's worth.
