My father was into imports at the time but back then imports were American cars
He had plenty of Pontiac's and even made a Pontiac car club, then later liked to restore older cars, some cars from memory
1968 Pontiac GTO 400HO with full options (like concealed headlights etc) which he swapped the 1969 455HO into.
60's Pontiac leman's (with big engines)
60's Pontiac Grand prixs (with big engines, 389 with multiple carbs from memory)
60's Pontiac Tempests
1967 Chevrolet Camaro (owned it briefly)
1939 Pontiac
1953 Pontiac
1927 Dodge brothers
1983 Pontiac Trans am (5.0L HO)
1979 Cadillac Coupe deville (was like new some old guy owned it)
1985 Chevrolet Suburban fully loaded
VW beetle (mum owned)
Mini (mum owned)
Datsun 1200 coupe (my mum owned it), great car my mum drove it and my dad never needed to work on it.
I would have forgot many but doesn't matter
He did import to Australia many many other cars for other people that include alot of Trans ams, Camaro's, Thunderbirds, Cadillacs, Lincolns etc. Also some of the cars I mentioned might not be interesting to Americans but they are very rare over here.
