Use the 75 from time to time, which is proper end driven, cherish it, love it, none of this more-modern Alfa stuff. Don't get me wrong, I'm sure the
164 is a fine enough piece of kit, but how does it compare to the 75 at the Alfa bits?Where's the V6 bit anyway?
If it compares very well... sell the 75, the 164 is more modern, blah blah blah.
If it doesn't compare very well... why buy it?
Yes, I know you want to use the 75 for track day use but such a glorious piece of kit to only be used from time to time... it just seems like such a waste... :-/
