Fantastic mechanic. The cost of changing the oil at a Mercedes dealership was $283.00. He saved me over $190.00. He showed up on time, with a great smile. He sure knows his business. Did a great job!!!!!

He is a really pleasant man,who has a good attention to detail,as it happens there was no way to get the car started, due to what appears to be failed fuel pumps,which is what i suspected. I am 70 years old,fixing it has lost its appeal,and did not have all the tools to fix it with me.Therefore being a mechanic my self in the past, i can only say he knows what he is doing.If the parts were at hand he would have repaired it no problem i'm quite sure,so for me he gets top marks,in all departments. Yours sincerely Barry Vare

I was very impressed with Theodore. I took a chance on using this mobile mechanic site and was nervous at what to expect. He came on time, did a really good inspection and made recommendations what I needed. I booked him because my driver side window was making a funny noise and I thought I needed to change the motor. He spent a good amount of time looking into the issue and explaining to me as he went along. I will highly recommend and plan on using him again.

All about Alternator Replacement

The alternator is the component that charges the battery in your car. When you use electrical components in your car (stereo, lights, etc.), the battery loses power. The alternator recharges the battery, replenishing the lost battery power. The alternator is located in the engine compartment. If the alternator is not working properly, your car will only stay running for as long as the battery has power stored. Once the battery loses power, your car will not start. Normally, a malfunctioning alternator will turn on the battery warning light or will have a low volt gauge reading.
