Been perusing the site, thought I would introduce myself and ask for some assistance at the same time!!

I’m used to classics, but more of the larger engine variety!! I drive the following Rover P5B as an everyday classic with a Jensen Interceptor as a my pride and joy (and money pit

I’m looking for a 2 or 4 door minor saloon, as nice as possible for my girlfriend, I would prefer a few modern upgrades (perhaps discs and a 1275 engine? Anything else worth having?) What sort of budget should I be looking at? What will I get for £2.5-3k. I liked the idea of a traveller, but that's been vito'd I'm afraid...
And does anyone know of any for sale in the London area?
Cheers,
Steve.
