It's a good offer but on the other hand.. you've spend alot of money on the car.
You could enjoy it a little bit more longer.
Like my gf said recently to me, how can you spend 600€ on a ICE installation and keep looking for other cars to buy. You've spend money on it, you can atleast drive until it's payed off and enjoy it for what it is (in my case).
And I actually give her right.
On a side not, I still have those 172 injectors laying around.. but what to do with them.
