Hi Michael,
Good luck with your search, I have been "driving enthusiastically " (but safely of course!) in my 1600 Coupe for twenty years now and still it amazes me, I can safely say I will never sell.
I counter act major surge by A: Provoking the slide/un gripping the tyres B: always making sure the oil level is on max C: using as Eric does a high quality 10-60 full synth. My Beta is approx 200 thou miles and all good.
Latest significant fail was tired old gear linkage bushes (Betaboyz ones excellent) and dizzy pick up gave up after 38 years!!! Must write to Turin and complain
I use the Coupe as much as possible in all weathers, family holidays etc and reliability is fine.
Spare parts and general understanding of these fantastic cars seems better now than ever before.
Obviously I cannot recommend buying one asap!!!
Enjoy the search,
Tim.
