I've had 3 Chevy's over the last 12 years. One I bought for $800 and only got rid of it because the wife wanted a van with sliding doors on both sides. The other one I got for $500, had it for 4 years, and sold it for $500 to get the money to buy a newer one with air conditioning. All three had 4.3L and over 150, 000 miles when I bought them, and I never had any trouble with them. Regular maintenance.
