i want to start selling the Used Mercedes, Audi , Jaguar, BMW and Volkswagen etc.. for very reasonable price.. compartively lower than whats in market price.
In Latvia, we have truly lots of "underground" car dealers already. The most known market is called "Rumbula" and located about 5 km from Riga along the Maskavas street. Before you open such business, I would recommend to visit Rumbula and check what's already suggested. I think you will be impressed, because we already have a great choice, despite most of such cars are scam in this or that way.
Besides of it, we have truly lots of smaller dealers located in other cities. Many persons do business getting cars from Germany, Italy or most likely Poland and Lithuania, and sell by posting private ads.
I think it's not a problem to buy a "reasonable" price car. Almost every suggestions are reasonable. But I think, the quality of such cars is less than average. You never know what could happen with such car in the nearest time.
Supposing the fuel prices will increase in the next time, I would say used cars are becoming even less popular in Latvia these days. Mostly only cars having ~1.6-1.8 l engines are on top of sales, mostly 2000-2005 years of production. These cars still may be sold for their normal price. I suppose you can sometimes buy 3.0 engine Mercendes or BMW of these years for less than a thousand of euros. Nobody needs such cars, they are too expensive in support and fuel.
Government taxes were dramatically increased for the couple of last years, too. You shall pay at least 100 EUR even per very small car like Golf or Yaris per year. Bigger car and bigger engine mean a bigger tax. And you can drive a car only 5 days without a registration.
So I think, if you need to build something solid and long-time, it's a question not only to exporting the cars, but also the investment you should do in advance in infrastructure, and it's not a small investment.
