<p class="MsoNormal"><span style="font-size:12.0pt">Agreed, as well. I can tell the difference between an MG TC, TD, TF, or a Triumph TR2, TR3, TR4, etc. from across the street.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt">But, yes, the spark plugs on new cars last 100K miles, there is not a grease zerk to be found. Exhaust systems, starters, alternators, water pumps also generally are good for 100K miles.

<p class="MsoNormal"><span style="font-size:12.0pt">These all were routine maintenance items in the past. No points, timing or carburetors to adjust on the new cars... <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt">That much said, changing the spark plugs on a MG TF is a great deal easier than changing the sparkplugs on a coil over spark plug on a turbo 4.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt">A friend of mine just accidentally dropped a spark into the engine bay of his 2019 C7 Corvette and it did not come out the bottom, but it had a pronounced harmonic rattle at about 2,500 RPM that was driving
him crazy.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt">We had to put it on my lift and use a borescope for about 45 minutes to locate the spark plug (it had wedged in the collector of the exhaust headers),and then another 15 minutes to fabricate an "extractor"
out of welding rod and fish it out.<o:p></o:p></span></p>

</div>
<div>
<p class="MsoNormal"><span style="font-size:12.0pt">The mechanical tolerances on the new cars are so much tighter and many of the materials are superior as well. Of course much of these improved tolerances and reduced maintenance is an artifact of the emission
standards that went into place 30 years ago and have been increasing (e.g., the exhaust and induction systems have to last a set number of years and a set number of miles)<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt">Yes, definitely more maintenance is required for the older vehicles, but also it generally is much easier/quicker maintenance. And I would also say, more enjoyable... :-)<o:p></o:p></span></p>
