Scottish Alfa Specialist?

Hi,

I've had my 164 3.0 Super (133K miles) for a year and a half now,
pretty much trouble free.
The first MOT was pricey at over £500, and it's nearly that time
again. A few weeks ago when I was changing the wing, I could see the
timing belt was looking pretty tired and worn. I don't have a full
history for the car (bought from a mate) so have no idea when,(or if!)
the last change was.

I only paid £600 for it, already doubled that with last years MOT and
the recent repairs I've had to carry out due to a drunk driver hitting
me. So, assuming there's nothing major wrong at the MOT I was
considering getting the timing belt done as well, as the engine seems
in great condition. I have been told to expect to pay around £400 for
the timing belt, can anyone confirm if that's about right? I would also
appreciate any recommendations for scottish alfa garages (I'm in
Glasgow but can travel) who would have the experience to do the timing
belt correctly.

I really should sell this car, what with the price of fuel here in the
UK..but it's soooo hard to part...!!

Thanks for any suggestions,

FrankyG
