Newbie car choice

[juce77]

Hi everyone.
Im wanting to get back into rc cars after about 12 years. Looking at 1/8 rallycross and cant decide which kit to get.

Think i have narrowed it down to either hotbodies d815 world edition or radiosistemi RR8 v2. What are peoples thoughts on these 2 kits?

Then ive got to decide what engine,servos and transmitter to choose any help would be appreciated,want to spend about £300-£400 on the engine and pipe.
