The old TX5 turbos was bacially the MX6 cept without 2 doors and 4WS. There alright cars, cept problems with 4WS, gearboxes were known as the weakpoint. The engines need a bit of work before you can up the boost a lot ie forgies, turbos should be the first thing to upgrade. The newer bubby shaped MX6 were a bit of a let down. Also timing belts should be done at 80000 (not 100000 like their handbook suggests)
I've seen this run and it would happily eat VX SS's.
This is the model I'm talking about

So long as your GF doesn't thrash a car, a well maintained MX6 I'd definalty consider.
