Ok, here's my list:
1: 1940-xx FIAT 500 (B) "Topolino" (Little Mouse) - it was a family car, hand me down.
2: 1960x FIAT 1100 (D) series - popular in India at the time.
3: 1973 Volkswagen Microbus - with the optional A/C package, included a weird bottom-of-the-chassis-mounted heat exchanger.
4: 1970-something Dodge Dart - the one with the 45-degree Inline Slant-6 Engine.
5: 1970s-something FIAT Spyder - this was a hobby car that I picked up for $250, rebuilt it from the ground up with my cousin and we sold it for $4000!
6: 1980 Honda Accord - my daily driver through college - loved that car, then I gave it to my brother after graduating and he promptly melted the engine block by driving it without oil in the crankcase - long story
7:1980-s something Honda Civic-CRX Si - the Pocket Rocket
8: 1985 - I think - Pontiac Sunbird LE - comfy little car, the LE package added some nice electric accessories and upgraded the stereo.
9: 1989 brand new Honda Accord
LX-i (was going to buy the new 1989 Honda Prelude 2.0 Si-4WS, but it just worked out this way financially...).
10: 2000 Infiniti Q45t - 10-year Anniversary Edition, #431/3000 made - still my current (somewhat) daily driver. Still only 45K miles on the clock.
11: Lexus
GX-470 w/Mark Levinson 14-speaker Audio Package (450W+dual subs - yikes), Nav + Towing packge - the weekend warrior.
12: Nissan Leaf all-electric - the in-town grocery-getter, the daily errand runner, etc. Nice that we drive it all day here in Houston, plug it in overnight and voila, good to go again in the morning.
Luckily - I have been fortunate to have driven some very eclectic cars - including that gorgeous Citroen DS that has been posted earlier in this thread - what a ride, with that Air Suspension!
My lady friend worked as a test driver for Porsche+Audi many, many years ago, she has an interesting list of cars that she has driven both on the test and offroad tracks for them.
Quite possible the weirdest vehicle that I have ever been privy to drive was a very heavily modified Land Rover Defender 90-series - except much older, it was a circa 1960s something model - it was modified by the military to do some heavy terrain climbing work (I used to live near the Indian Southern Command army base in Pune, India) - and they would drive this thing around our neighborhood streets from time to time.
One time, the soldiers operating it - they were pretty friendly with the neighborhood kids and car afficianodos back then - this was in the early 1970s - they just let me get behind the wheel and take it on a ride on a test strip that they had made on base.
Something about a teenager - me- driving an armed (live ammo) army vehicle, taking 45-degree inclines, 25-degree side banks and climbing over rocks while the soldier above my head behind me was firing off live rounds at targets!! Well, that'll never happen again, for sure.
Well - there are other cars that I have co-owned and otherwise had access to on a daily basis, but the above are the ones that I have personally owned.
