Is it safe to prurshase a 2007 bmw 328xi with 148,720 miles?

That's a lot of miles but doesn't mean it's bad. Recommend taking it to a mechanic before purchasing.

I trust high-mileage BMW's about as far as I can throw them......that being said, if higher mileage is what you can afford, stay away from anything european. They always cost a lot more in maintenance and repair costs. Toyota, ford, chevy, gmc, hyundai etc. are better options in moderately used vehicles.

BMW-MERCEDES:lots of folks,not everybody wants one to keep up with the JONES'ES!! OR JUST LOOK GOOD GOING DOWN THE ROAD!UNTIL THEY HAVE TO HAVE THEM WORKED ON,THEN THEY NEED DIAPERS?SOME FOLKS CAN AFFORD THE CARS,AND SOME CAN'T.BUT IF YOU WANT IT AND HAVE A FAT CHECK BOOK,GO FOR IT.otherwise see the 2nd answer!
