Just out of interest, why did you buy the NISSAN ALTIMA (2016) rather than the HOLDEN COMMODORE VF (2016)? The Holden is the recommended car to complete this series according to the RR3 Wiki:Upgrades Strategy For 100% Completion and therefore the one you can safely upgrade the most.

Some research might have saved you some pain:
 * To open the next series you need 33 trophies
 * The Altima only needs to be upgraded to PR 55 according to the strategy
 * Trophies for time trials don't count
 * Trophies for cars you don't have don't count
 * There are only 32 trophies that the Altima can complete with PR 55 (assuming you can reach them all)
 * You will need to over upgrade the Altima to at least PR 56, probably 57 or 58 and maybe even 61 to open the next series.

If you can still cloud restore and change your mind it might be your best bet. In future, might be worth asking the question about which car is best to buy first.
