Unfortunately you’ve picked the weirdest week to start. It’s week 13 of the season which is a sort of last week of school party season where the series we all usually race in aren’t available.
Season 2 starts next Tuesday. I can’t remember what class the Jetta races are in but it might be that you need to move up to class D before you can race in that series.
I know @Alex and I have moaned a bit about the mx5s but it’s by far the best place to start imo. The whole series is designed by default to be the intro series. I had some amazing races in there which I wouldn’t have had in a series where the field was more spread out.
The cars handle brilliantly; the tracks in the series are the ones you already own when you first subscribe, and participation is super high which means you’ll get loads of well matched races and you’ll get away with a lot of mistakes as everyone in there is still learning.
If I were you I I wouldn’t buy a single car until you’re A/ confident you like the game B/ are confident you’re not going to punt anyone else off. If nothing else, car contact can send your safety rating tumbling.
