I can tell you that the SVT has a tight go-kart like feel to it, as compared to the bulky and crude SHO. Build quality is much better too. The suspension and chassis are superb. Also shifter and clutch are buttery smooth compared to the SHO. Road and wind noise aren't that great. Back seat is really quite comfortable except for lack of headroom (I'm 6'3 and sat back there for several hours on a trip) Front seats are excellent. Engine isn't as strong but sounds so OMG beautiful.
Problems to look for ... most are minor, but the trans syncromesh on earlier cars can fail. Differential is somehwat weak also. Shift smoothly and avoid burnouts if you want it to last. Wheel bearings, water pumps, precats and O2 sensors have been known to fail. Trick polished intake manifolds become coated with carbon every 30-40K necessitating a cleaning to restore power and gas mileage.
Engine can become oil starved if right-cornering hard at high revs and throw a rod bearing.
But otherwise, you'll be hard pressed to find a FWD sport sedan that corners as enthusiastically and sings as beautifully as the SVT Contour
