It's not that difficult:
 * Don't care about full garage or 100% complete - Upgrade RENAULT R.S. 01 for 424
 * Do care about full garage - Buy PORSCHE 911 RSR (2015) for 536/670

If you care about a full garage or 100% completion then you need to buy the Porsche eventually and so the upgrades on the Renault would be a sunk cost.
