Welcome to my Top Line Repair Facility for your Jag. So often repair shops who claim to specialize in Jaguar® miss-diagnose Jaguar® problems and sell customers expensive parts that the Jaguar® did not need. One reason these shops end up costing more is because they miss diagnose Jaguar® problems and they leave the parts on the Jag , that you already authorized , rather than remove them. Parts Places don’t take return on electrical parts so when this happens the Jaguar® owner usually gets a call asking for authorization to install yet another part that the Jag ” needs”.  It takes a great deal of expertise in Jaguar® Diagnostics to identify the small problem immediately and not ignorantly replace unneeded parts to find out what the problem is, CHARGING YOU EVERY PENNY FOR THEIR IGNORANCE.  Top Line Jag Repair’s elite Jaguar® Technicians find the small short or loose connection rather than an expensive ECU that so often the Computer is telling the lessor qualified ( in Jaguar® diagnosis) mechanic at a repair shop to replace to fix the “CODE”!!! . Top Line Diagnostic staff has the talent to identify Jaguar® specific repair both electronically and mechanically which is becoming a lost ability in our trade.  We have The Jaguar® Factory Computer and EXPERTISE on Jaguar® to identify repairs that a regular mechanic will not see until its a big problem costing the Jaguar® customer lots of money.

In fact, other shops throughout the Metro area send their Jaguar® repairs to our Top Line Jag Shop when they can’t determine the problem, yet they still charge you significantly more than our price to do the Jaguar® repair service.  Most automotive repair shops and dealers pay their mechanics commission, potentially leading to strong motivation to complete each job quickly and overlook potential bigger problems down the road. Our team of Jaguar® Mechanics & Jaguar® Technicians are paid SALARY not commission or bonus and they do NOT accept tips. This cuts out any incentive to make unnecessary or costly repairs, yet still provide exceptional service.

We do NOT employee Service Writers ( these are the people talking to you, selling you your repair work, who are usually on Commission and make as much as or more than the top earning technician at the repair facility or dealership), this cuts out a big chunk of money that is normally added into your repair invoice somewhere else . Here at Top Line Jag Repair you will SPEAK DIRECTLY WITH YOUR DIAGNOSTIC TECHNICIAN who is working on your Jaguar®, who is ON SALARY.

SPECIALS And Money Saving Coupons

Here at Top Line Jag Repair we understand the importance of using GENUINE JAGUAR® PARTS.  These parts are made specifically for for your Jaguar® and are warrantied for 12 months.  Specific Oils and fluids, gaskets, hoses, transmission cooler lines, oil filters, CATALYTIC CONVERTERS, and many other parts for your Jaguar® need to be made specifically for your Jaguar® and should not be aftermarket. Using aftermarket parts in many cases with your Jaguar® will cost you more money in the long run. So many aftermarket parts are not made as well as the Genuine Jaguar® parts and wont make it out of warranty and if they do often wont make it very long past warranty causing the consumer to pay again to have the job redone.
