Заказывал стартер "Bosh", доставлено в срок к дверям моей квартиры. Упаковано тщательно, сохранена заводская упаковка стартера. Благодарю! Пока ещё не установил стартер. Надеюсь, будет работать долго!

My commercial fishing boat had an issue after 48years and we lost an exhaust elbow. I emailed barr marine and they said they still make those parts, but they don't sell to the public but explained that there are many that sell the parts I was looking for. Your company had most of them and I purchased from another company to get the all parts I needed for the repair. I'm still amazed that I found the parts I needed and that the original company still makes them. Your site was easy to navigate and shipping times were short . Will direct others to find what they need. Thank you.

Thank you

Found the part I needed , in order to finish my project ,without driving to town and going through hundreds of fittings to find the right one.
