There are often very cheap deals for new subs for a few months, and if you love it you can resub on black Friday for a discount also.
I've definitely spent a lot more on it now, but I also took a loooong time to spend anything more than the sub price. And now there's even more base content than when I was new. I was happy racing the mx5 for ages before being tempted into any purchases. Now you got those, GR86, Vees, FF1600 and more, all great cars. Plus oval stuff
