What to buy?

Shortly after the game came out Xbox gave me a five euro voucher and said it was for FH6, not sure why but I used it to buy some car vouchers.

I used a couple on cars I wanted to finish certain tasks when I had no money. I still don't have much but given I have 3 vouchers left and the cars can't be sold if bought with a voucher, what would you recommend?

In FH6 I made the mistake at the start of the game with the voucher they gave us of just buying the most expensive car, which I then not only didn't use but got one in a wheelspin anyway.

To give context I prefer off road or rally races, however I do play all.

In FH 5 and FH5 my favourite car was a focus that I tuned up to be the perfect rally car, and so far I've been enjoying the welcome pack Tacoma in FH6.

All suggestions welcome :)
