My dad‘s 1960 Porsche 356 beers been sitting in my garage not running for the better part of 10 years. I finally decided to get it back on the road where it belongs. John Hollaran and Hollerans Performance came highly recommended. I contacted John and gave him the backstory on the car and got on his schedule. Just got the car back today and it runs fantastic. More importantly it also stops now as well. During the whole process of going through the car to find out what was wrong and what needed to be repaired, John stayed in constant contact with me and gave me updates on the progress. I couldn’t be happier with the work that he did on this car. If you’re looking for a high-quality, high integrity Porsche mechanic that services newer Porsches as well as classics then I highly recommend you contact John Holleran at Hollerans Performance. You won’t find better. Thanks again John.
