I bought my 147 from Cleveland Cars last July in Ash (Aldershot). After Sales was a bit crap but the salesman was knowledgeable and friendly. Unfortuately for parts you have to wait a good 15 or 20 minutes while they go out back and have a cuppa before taking the tin of oil off the shelf for you. A friend also bought a 147 from there and has had real problems with it and Cleveland Cars have been awful to him. I will not be going back there.
I have booked it in for its first service with Bishops in Guildford for next Saturday and they seem a lot nicer there. They also have a 156GTA which I will be testing one day this week!
I've had experiances with both Perry's of Portsmouth (purchased car from there) and Autotehnique (sp?) (12k service) in Salisbury. Both have been very good and profesional.
I've had numerous problems with the 147, although it is taking time to get them sorted I can't fault Perrys on their help!
