Nothing new with this event
3 hours instant upgrades and servicing
Tab 2.3 goes from the massive 0.1 pr start to 1.1 required, although I did struggle to hit the speed snap figure for 2.2 with no upgrades 
The acceleration from a standing start is something to witness ( I’m sure 0 to 100 kph can be done in just under an hour)
Good part is first 3 rounds of all upgrades cost just under 50 gold
Edit - and I forgot to mention there is a truckload of gold waiting at the 25% mark A whole one (1) gold
