are those 3000€ bone for the car or with everything as with insurance ect.?
in germany you could get far with 3k€ for a used car but i'm not sure how the situation is in Latvia...
also it depends on what you want. if you would like a small car with 100hp or something like that it could be easy to manage. but driving fast isn't the best thing for a beginner (imo, i'm actually glad i 'only' have a ~50hp ford fiesta, nice for cruising but you can't drive fast with it)
of course a fast car is more fun. you'll just have to sit back and think about it, what do i want? and how far can i get with that 3000€ i got? see some local dealers ect
don't rush your decision or do what other people tell you to do!
