At this point, I wouldn't recommend spending gold to progress in the game as there is a new update coming just over a week. I'd save your gold and use it to ensure you can get as many of the cars in the next update.

Winning cars in Special Events, LTS and Flashbacks is the cheapest way to obtain cars and given your gold balance I would suggest you could afford to get some of the cars still on offer in this event. You just about have time to do both the flashbacks and you can run them at the same time as the LTS. An estimate of the costs:
 * Relentless - minimum of 204 for 90 reward
 * Rennsport Redefined - minmum of 295 for reward
 * Lamborghini Huracán LP610-4 Championship - 254 for reward

So for a minimum spend of 753 you could have all three cars with significant upgrades and a rewards of 250 meaning a minimum net spend of 503 which should leave you with over 1000 still going into the next update. It might cost you more, depending on your skill level, I don't remember how hard the two flashbacks were to win the cars for an average/new driver.

Personally, I'd do the one of the flashbacks and see how it goes, start the second and if it looks like you can win them for a reasonable amount then do the LTS as well (it's open right up to the end of the update).
