Looking for an E46 325 as a second car for myself - have a strong preference for a convertible as never had one before & time is ticking on! And, never say never but I plan for this car to be driven into the ground.

Planning to enquire on three cars I see listed on carzone - 1 private sale & 2 dealer sales - all are comparably priced & mileage.

Wondering if anyone knows much about the dealers:

Private sale one is this one:

Obviously, given the mileage I'll be checking for major service work to be complete & should I decide on one of the above I'd look to have that car checked (AA, RAC, etc).
Is there anything specific to the E46 325 I should be aware of? Would the manual be a better option over auto? Note, I have never drive van E46 325 before.

Any opinion on the asking prices?

All/any feedback is very welcome.
