Ok, it’s time to look once again at Shifty’s used cars. Here's a video of everything available:
However, it does pain me to point out, it appears the same cars are available that have always been there…
Which, I’m starting to think is all there is… which means the front cover of this game LIED to us. It’s bad enough we don’t have a MR2, but the cover promised us a Soarer and a NSX!

This is false advertising! Someone call the Japanese Consumer Commission circa 1993!
…Anyway…
Same deal as before. You Goons are responsible for our next choice!

This time around, we want something a bit more serious this time to compete in the higher tiers, so I’ve removed the Kei cars and the off-road four wheel drive cars. (Seriously, why are they in this game?)
We now have $30,000 at our disposal, thanks to Hiro’s incredible luck and perhaps a bit of save state scumming. Note, Hiro does go into negotiations, so the end cost will be a a bit cheaper, and (I assume) we could even get the Fairlady Z, even though it’s slightly above 30.
Whatever money left over can go into mods, but the interface also leads me to believe that we can transfer any mods we’ve made from the Jimny to a new car as well. So that's nice.
Incidentally, my pick is for the Nissan Pulsar GTi-R, because that's a hell of a lot of car for the price - but there’s alot of great choices here.
