Why be subject to $60 per hour repair shop rates. The to-and-from's and gas money spent. The prolonged wait periods and questionable mechanic practices -- when a great number of projects are just a well accomplished, diying. Aim for savings in terms of time, money, and aggravation spent in all these areas on your foreign and domestic vehicle.
Not to mention the peace of mind that comes from seeing the actual parts before they are installed.
