What do you think of this car?

Hello! I’m interested in this car:Click here!/ It has a few kilometers, only I don’t like the age. The car is from 2012. The seller has promised me that I can do a purchase test with the car. Can the ARBÖ (the ADAC in Ö) do a complete purchase test with such a complex car? I’m particularly concerned about the battery – 8 years is already a lot, and AFAIK has Toyota 8 years on the battery. Can it be that the seller wants to get rid of the car? And still as funny things tells like 136 hp – which the car has only on demand and for 5-10 minutes. Another car looks better, but is also more expensive:Click here! LG, Smart
