I really need some help to complete my cars collection

First of all, the majority of games I play are racing games, and after playing Forza Horizon 2 and 3, I can safely say that Horizon 3 is THE BEST car game that I’ve ever played. Period. Never had so much fun.

With that said, I have to say that I’m almost done with the game because I can’t play the online part of it due to my internet connection to be freaking bad, to say the least. So I can only (luckly) play against my friends’ and club members’s drivatars.

I’m gonna cut to the chase here. I’m trying to buy every single car avaliable on the main vanilla game (DLC does not apply), and I’m almost there. There is only 19 cars to go. But the thing is: THE DAMN CARS ARE SO EXPENSIVE!

There are those 10.000.000 priced cars, and also a few a little below that range. I’m so tired of racing at goliath, albeit it is very fun to play though. The best I could do was a 6 hour 36 laps race on it, and I was dead tired at the end. I did other shorter races on goliath to gather money. I’m past level 700, so wheelspins are not so worthy anymore and very hard to earn.

Now to the question: Is Goliath Circuit racing the best and fastest way to win big money on Horizon 3 if you’re past level 700 or so? Or is there another route I could take to accomplish my goal?

The best I can do is race at Goliath with my Viper HE with CR boost and also the 2x CR multiplier perk. It gives me around 1.1Million per hour, but it’s too tiresome. Any sugestion is really appreciated.

Thanks in advance.

This is the best method I have found.

In addition, I am a member of a club and usually race enough during the week to get the 400k bonus, which along with my Tier 11 500K bonus nets close to another million each week.

Yeah, Goliath in a credit boost HE car with both the Doubledown perk and the perk that gives you 3x XP for skills is the fastest way to make money driving.

Edit: at level 700 it’s the best method.

I made my mind up to by my first 10 mil CR car and did this to get the last 5 mil CR last night.

I was afraid about racing at goliath with a CR boost car and the perks being the best option to achieve my goal, 'cos its very tiresome. But with your confirmations, I think it’s the only way indeed.
Anyway, thanks very much for the help, guys. Really appreciated.

If you have VIP it’s much more effective to use either an XP boost car, or Skill boost car, even over level 500 where it takes almost 100 000XP to level up I’m still getting more credits from wheelspins than I did running a credit boosted car. Best method I’ve found for me is to take the HE Camaro, fully upgrade it with the LS3 swap, then blueprint a race with all the classic muscle cars minus the Boss 302s, since they’re the only one that seems to keep up, that way you can spend the whole race drifting unopposed, and still have the top speed.
