Well, I have a garage/game called "allstars" in which I collect my "allstars".
Some cars get in there just because they're hard to obtain; all three license test prizes for instance. And they're not necessarily the best cars; perhaps useful for some particular lower series, and/or just interesting.
I would tend to rate the Cerbera LM higher than other people seem to. I don't even seem to have a yellow or purple Concept Car--I think they got disgraced by the drug tests.
I'm having trouble picking 10 from those 40, so here they all are. Some are duplicates anyway...

Removing duplicates actually gets down to 27.
Not sure why nobody included the Nismo 400R.
I found the 180SX'94 a really good balance for when I was good at the Hard-Tuned Series.
The Pulsar is a real sleeper. And can be used as a starter car if you happen upon the right days.
The Nissan Silvia '88 K's 1800cc is probably the best starter car which can later win all races it can enter.
The R32 GT-R'89 was an amusing monster when learning the game, as were the Mitsubishi GTO twinturbos. Not sure why I didn't put the '95MR into this garage.
Now, I went back and did an ordered choice, indicated in first column.
This results in...
01 [R]TVR Cerbera LM (prize UKvsJP)
02 Nissan Silvia '88 K's 1800cc (used)
03 TVR Griffith 4.0
04 Toyota Supra RZ (prize Normal)
05 red Nismo 400R (prize Super license)
06 Nissan 180SX'94 Type X (used)
07 Subaru [R]Impreza WRX-STi version III (prize Normal)
08 Nissan Pulsar '91 GTi-R (used)
09 Mitsubishi Lancer EvoIV GSR (prize, 4WD)
10 Mazda Demio Aspec (prize Sunday)
Another car worthy of mention on one or both lists is either showroom Viper, especially when race-modded. The GTS race-mod is a lot more attractive-looking, though. And I'm not sure why the MA70 Supra isn't there either.
