At an advanced age (79) I'm finally looking for the 7 that I've lusted after for a few decades and am doing my homework. My budget is limited (no recent model street rockets). I'm interested in a Caterham with heater and weather gear for mountain road use primarily. Might do a track day or two at some point (currently have old/slow Porsches).
I'm familiar with crossflow Fords (from Formula Ford racing) and know a bit about Duratec motors and would prefer either of these. I've also seen several K-series cars for sale. I've read through the PistonHeads writeup, which was very helptul. It appears that (other than an older head gasket problem, these are a solid alternative for a 7. I'm interested in other experiences, particularly US, with these engines as far as longevity since a rebuild might be more troublesome that either of the other two alternatives.
Thanks for any input.
