I hope you find a 145QV Nem, they are such a great car. As Rick says I did have a 1.8TS at the same time as the QV. It had 140bhp compared with 150bhp of our QV. The torque figure is quite abit higher for the QV though and you do feel it. Its obviously quicker and also sounds better. The 1.8 is less smooth, gets alittle rough at the top end and bellows rather than screams and rasps. The QV has a harder ride and to be honest doesn't really handle any better, just has a worse ride.
When I sold the 1.8 I was actually wanting another 145QV, possibly a facelifted one (2 QVs, what extravagance) but managed to get a good deal on the 156.
I go for a QV over the 1.8. The only downside is the harsh ride, but everything that really matters ( engine, looks, performance ,engine,engine)is better.
