Tifosi (Ferrari) or Murk (Mercedes)?

Are the Tifosi engines or Murk engines better and is it worth switching from Rednote (Renault) to either of them?

Murk, and probably.

I have Murk, Seashells as fuel and the Bridgestone one.. Think it's Bridgerock

Murk by miles!!!

Ok. But if I want to transfer Engines, would the cost per engine effect the performance? So if I only pay 300,000 for an engine would it be worse than if I had payed say 600,000, or is there only 1 engine model from each manufacturer?

Try to pay as little as you can

Ok I will, I might stay with Rednote for a while because I have a 30 race long contract. :3...

I wouldn't wait. The difference is significant.

Ok, I put an offer of 320000 each of which they both rejected so I will go with 360000 after the next race! My primary choice is Murk.

Murk is a lot better!! I had tifosi till Valencia in a season I just finished before Valencia I got murk and got 1-2s at every race of the season apart from monza where I got 2 punctures on each car!

Wow! Ok, I am actually going to go on my youth account and replace Ferrari right now then!
