Aaron,
Which of the British rides has the ORIGINAL paint? (if any)
Which of the two is painted British Racing Green?
Which has not had any cancer treatment?
The '67 BGT happens to be "the ultimate year" for these automobiles......unless one "requires" an early door handle model with the 3 main bearing engine.
The Tr6 happens to have a FANTASTIC exhaust note....especially with a set of headers and a free flow exhaust....Top down motoring has its charms.
The cancer syndrom weighs heavily in this equation.
When you mention your previous Tr4....sounds as though that it was wonderful!
Enough jabber.
I say loose the 450SL IF you must...however, when one has owned a vehicle such as this since NEW, then perhaps that in itself warrants it as a KEEPER.
Otherwise, all things being equal...I would keep the MGB GT, sell the Tr6 (because the Triumph is of a LATER variety).
If ANOTHER Triumph comes into play, I would attempt to locate a 1968 Tr 250 (or even the european Tr 5).....the early Tr4 body has always enamoured itself upon my psyche....when mixed with the early 6 engine, this one year only ride is sweet.
Then again, the 1967 MGB ragtop is quite nice...
We will not even get into early Lotus Elans (1960's) and even the E types and earlier XK's.......my older brother had a 1961 Big Healey (complete with side curtains) as his first car.....As a child my Dad used to borrow it so we could travel from Ct. to Boston and visit my older brother in the early 60's.....That automobile introduced me to TOP DOWN MOTORING
Best wishes always and we trust that you WILL make the CORRECT decision
