Just to add support to another contender, +1 for the MG TF. For 3k you could get a to spec 160hp VVC. Ideally look at a 2002/3 model for the best specification.
Surprisingly spacious for a 2 seater and capable of taking a bike on a boot mounted rack or with the wheels off, on the passenger side. Room in the boot for a weeks luggage.
High revving engine on the VVC which really works well with being thrashed, but doesn’t need to go fast to be fun. Shines on B roads & can put many an Audi or BMW to shame through the corners.
Budget for a head gasket at some time, but if you can do it yourself it’s not expensive, and if you treat the car right, you may not even need it.
